We use a MRI Carotid Artery Angiogram (with the option of a CT Carotid Artery Angiogram in those who suffer from severe claustrophobia) to determine whether there is any narrowing of the neck arteries that supply blood to the brain. This would indicate an increased risk of stroke.
If any narrowing is considered severe enough, a procedure can be undertaken to ‘clear’ the blockage and reduce the risk.
